Whitelist domain name registry

ABSTRACT

Systems and methods for managing domain name registrations in accordance with rules and regulations of a domain name verification system are disclosed. The disclosed technology enables a domain name verification system to regulate the registration of domain names in accordance with its own domain name registration policies. This disclosed system uses a “whitelist” domain name registry to register “whitelist domain names” once pre-approval to register a corresponding target domain name has been granted. In this manner, the whitelist domain name registry system acts as a repository for pre-approved domain name registrations and enables pre-qualified registrants (including potential or prospective registrants) to then register a target domain name.

CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a continuation of U.S. patent application Ser. No. 14/985,005, filed Dec. 30, 2015, which is hereby incorporated by reference in its entirety.

BACKGROUND

The Internet connects computers, computer networks, and users throughout the world. Computing resources, such as web servers, connected to the Internet are each assigned an Internet Protocol (“IP”) address that represents the online “location” of that resource. IP addresses, which are defined by a set of numeric values (e.g., 143.254.4.17 (IPv4) or 172f:ad57:cd40:d089:4fe4:d1e1:100d:5b31 (IPv6)), are often difficult for humans to remember. Domain names, such as “acme.com” or “acme.net,” which are often easier for humans to remember, provide a convenient alternative to IP addresses. Rather than remembering and entering an unremarkable string of numbers to access a website, a user can simply enter a corresponding domain name. A domain name is a string of characters (e.g., numbers or letters) specifying a top-level domain (“TLD”) (e.g., .com, .net, .org, .guru) and one or more sub-domains. For example, “acme.com” comprises the sub-domain (or sometimes called the second-level domain or “SLD”) “acme” (which is itself comprised of a string of characters, or sometimes called simply a “string”) under the TLD “.com.”

Domain name registries (e.g., NEUSTAR, Inc.) are entities that administer or operate TLDs. In the domain name industry, registries serve essentially as “wholesalers,” and only rarely interact directly with domain name applicants, or registrants, who wish to register domain names. Typically, domain names are registered through registrars, which serve as the domain name industry's retailers and may be accredited by the Internet Corporation for Assigned Names and Numbers, or “ICANN.” Each registry (or “registry system”) maintains databases of currently-registered domain names, each database identifying the SLDs that are registered in a corresponding TLD, who holds the registration, and other identifying information and can provide access to this information via various databases and servers, such as WHOIS servers, Domain Name System (DNS) servers, Registration Data Access Protocol (RDAP) servers, Registration Data Discovery Service (RDDS) servers, and so on. When a party wishing to register a domain name submits a corresponding request, the registrar submits the request to the relevant registry. If the domain name is available (i.e., not then currently registered), the registry typically allows the domain name to be registered to the first requesting party. As an alternative to this “first-come, first-serve” system, registries may auction domain names, use “sunrise periods” (during which qualified claimants with certain rights to marks, such as a trademark, are offered preferential registration rights), and/or offer rights of first refusal. Currently, ICANN controls the addition of new TLDs to the root domain name server, which then makes those TLDs available to users of the Internet.

DETAILED DESCRIPTION

In some cases, a domain name registration may be subject to control or oversight by a domain name verification system (“verification system”) or domain name registration manager. A domain name verification system may be under the control of a registrar, a registry operator, a third party, or any combination thereof. For example, certain registrations may be subject to control or oversight by an authority (e.g., a government) due to the contents or meaning of the domain name, the identity of the registrant, the identity of the registrar, the TLD's rules, or any combination thereof, and so on. The domain name registry responsible for a particular top level domain (or a subdomain name thereof) thus may require pre-approval before allowing registrants and/or registrars to register a domain name within that top level domain (or a subdomain thereof). In some embodiments, the disclosed techniques are an extension to the domain name system and other systems that underlie the Internet and enable intermediaries (e.g., verification systems) to oversee the registration of domain names in an automated and efficient matter.

Systems and methods for managing domain name registrations in accordance with rules and regulations of a domain name registration manager and/or verification system are disclosed. The disclosed technology enables a domain name registration manager or verification system to regulate the registration of domain names in accordance with its own domain name registration policies. This disclosed system uses a “whitelist” domain name registry to register “whitelist domain names” once pre-approval to register a corresponding target domain name has been granted. Once the registrant and/or registrar are established to be qualified, the facility can generate a whitelist domain name for the whitelist domain name registry (e.g., “registrantID.registrarID.donuts.domains.valid.zone”) and register the generated whitelist domain name with the whitelist domain name registry. In this case, the “valid.zone” subdomain of the “.zone” top level domain acts as a domain for registering whitelist domain names. Thus, the “valid.zone” subdomain is a “whitelist domain” for registering whitelist domain names. Subsequent attempts to register the domain name “donuts.domains” can be checked against the whitelist registry to determine whether the registrant and/or registrar attempting to register “donuts.domains” is/are pre-approved to register “donuts.domains.” In this manner, the whitelist domain name registry system and its associated DNS server act as a repository for pre-approved domain name registrations and enable the pre-qualified registrants (including potential or prospective registrants) to then register a target domain name.

In some embodiments, the disclosed system includes multiple domain name registry systems, including one or more whitelist domain name registry systems (where whitelist domain names are registered) and one or more target domain name registry systems (where domain names for accessing sites via a network (e.g., the Internet) are registered). The whitelist domain name registry system receives, from a domain name registrar (e.g., GODADDY, ENOM), a request to register a target domain name (e.g., “website.domains”). For example, the whitelist domain name registry system may receive a set of one or more commands to register the target domain name, including an indication of the domain name, registration credentials (e.g., credentials for a registrant, credentials for a registrar, etc.), and so on. If the whitelist domain name registry system determines that the requested registration is available and subject to control or oversight by a verification system, the whitelist domain name registry system submits a request to the verification system, which can either approve or deny the request. Each verification system may specify various requirements for approval. For example, a government may require both a) a review and approval of a registrant's identification and/or b) a review and approval of a domain name to confirm that the domain name is not prohibited or otherwise reserved (e.g., a verification system may first verify that the requested domain name does not include any obscene or otherwise offensive language before approving the request). Each verification process may be performed automatically and/or with human input. In some embodiments, if the verification system has not yet reviewed or approved an application (e.g., if verification is pending for the application), the whitelist registry can withhold the registration from the DNS and other servers (e.g., a WHOIS server) by placing a “hold” status on the whitelist domain name, such as a server hold. In this manner, subsequent attempts to register the whitelist domain name can be blocked until the hold on the whitelist domain name is removed. Once the verification system provides an indication that the registration is approved (i.e., verification is approved), the whitelist registry system can remove the hold. Otherwise, if the verification system denies the application, the whitelist registry system can delete the registration entirely, thereby removing the hold. Furthermore, if the registration application is approved by the verification system, then the hold on the whitelist domain name can be removed and the whitelist domain name can be published (e.g., in the whitelist registry system DNS server and/or other servers). In this manner, the system can apply a first come, first served order to registration of whitelist domain names. In some embodiments, the request may include credentials for the registrant and the registrar, such as a user identification and password, a secure token, government issued proof of identification (e.g., passport, driver's license), and so on. In some embodiments, the system may require verifiable or authenticated credentials. In some cases, the system may rely on uncertified credentials. In some cases, the generated whitelist domain name can be identical to the target domain name.

In some embodiments, after the registration is approved by the verification system, the whitelist domain name registry system generates one or more whitelist domain name versions for the requested domain name for registration in the whitelist domain name registry system. For example, a whitelist domain name may be generated by concatenating some combination of identification information for the registrant, identification information for the registrar, the target domain name, “.”, and/or a predetermined top-level domain name (or a subdomain thereof) corresponding to a whitelist domain name. For example, for a registrant named “John Doe” attempting to register the target domain name “website.domains” via registrar GODADDY, the disclosed system may generate, as a whitelist domain name, “John_Doe.GODADDY.website.domains.valid.zone.” Registering this whitelist domain name in the whitelist domain name registry system indicates to other domain name registry systems that “John Doe” is pre-approved to register “website.domains” via registrar GODADDY. This indication can be communicated to the other domain name registry systems via, for example, the DNS, the RDAP, the WHOIS, RDDS, protocols, and so on. In some embodiments, the disclosed system may generate multiple whitelist domain names for registrations, such as “John_Doe.website.domains.valid.zone” (indicating that “John Doe” is pre-approved to register “website.domains,”) and “GODADDY.website.domains.valid.zone” (indicating that registrar GODADDY is pre-approved to register website.domains on behalf of at least one registrant). In this example, the subdomain name “valid.zone” is employed to register whitelist domain names. One of ordinary skill in the art will recognize that other top level domain names (or subdomains) may be employed for whitelist registration purposes (e.g., “valid.zone,” “whitelist.domains,” “safe.systems,” “.whitelist”), including non-English domains and subdomains that include non-English characters (e.g., “

zone”). In some embodiments, one or more of the components of the whitelist domain name may be encrypted before and/or after being combined with other components, including, for example, applying a cryptographic hash function (e.g., SHA-2 (Secure Hash Algorithm 2), MD6 Message-Digest Algorithm) to the components and/or composition(s) of components. One of ordinary skill in the art will recognize that other cryptographic hash functions or encryption techniques may be employed. Furthermore, each verification system may establish different procedures for generating whitelist domain names, such as different components, different whitelist domains, different orders of the components, and so on. In some cases, a verification system may receive registration requests directly from registrants or registrars and, upon approval, register a corresponding whitelist domain name or names with a whitelist domain name registry system.

In some embodiments, after the whitelist domain name(s) are generated, the disclosed system registers the generated whitelist domain name(s) with the whitelist domain name registry system. The disclosed system can register whitelist domain name(s) using a standard Extensible Provisioning Protocol (“EPP”) message for registering domain names. Once the whitelist domain name(s) are registered, the whitelist domain name registry system can be used to determine whether a registrant and/or registrar is/are pre-approved by the appropriate verification system to register a corresponding target domain name. However, registering the whitelist domain name does not register the target domain name.

In some embodiments, after registration of a target domain name has been approved by, for example, registering the appropriate whitelist domain name(s) with the whitelist domain name registry system, the registrant or registrar may submit a request to register the domain name with the appropriate domain name registry. If the domain name registry determines that the registrant, registrar, and/or domain name are subject to oversight or control by a verification system, the domain name registry generates one or more whitelist domain names in accordance with the procedures established by the corresponding verification system. The disclosed system then checks an appropriate whitelist domain name registry system to determine whether the newly-generated whitelist domain name is registered. These checks can be performed by, for example, querying the WHOIS or DNS server of the whitelist domain name registry system, sending an appropriate EPP communication to the whitelist domain name registry system, and so on. If the whitelist domain name(s) are not registered, then pre-approval to register the target domain name has not been granted. In this case, the disclosed system denies the registration and notifies the appropriate registrant and/or registrar of the failure.

In some embodiments, after the system determines that pre-approval to register a target domain name has been granted, the system determines whether the requesting party or parties are the same party or parties that were granted pre-approval. For example, the request to register the target domain name may include credentials for the registrant and/or the registrar. These credentials can be compared to registration information stored in the whitelist domain name registry system in association with the registered whitelist domain name(s). As another example, if the procedures for generating the whitelist domain name require unique identification information for the registrant and/or registrar, the disclosed system can at least partially validate the request by the existence of the whitelist domain name(s) in the whitelist domain name registry system. For example, if each whitelist domain name is generated using a registrar's IANA number (i.e., a unique value assigned to the registrar by the Internet Assigned Numbers Authority (“IANA”)) and a unique identification number for the registrant (e.g., a government-issued identification number), then the whitelist domain name itself includes identification information and can be used to validate both the registrar and the registrant. Alternatively, if the whitelist domain name is not generated using unique identification for the registrant and/or registrar, then other identification means may be employed to verify the identity of one or both. For example, the system may retrieve identification information from a record stored in association with the registered whitelist domain name(s), such as a DNS TXT record, a DNS NS record, a DNS A record, a WHOIS record, and so on. In this manner, the system protects against registrants and registrars who have not been pre-approved to register domain names for which others have sought and received pre-approval. One of ordinary skill in the art will recognize that the identification of the involved parties may be verified using any number of means.

In some embodiments, once the registrant and/or registrar are verified to have pre-approval to register the target domain name, the system registers the target domain name with a public domain name system server, which enables traffic to be directed to the registrant's site using the registered target domain name. In this manner, the registrant is able to register the target domain name after seeking pre-approval for the registration from a verification system and having a corresponding whitelist domain name or names registered with a whitelist domain name registry system.

In some embodiments, various components described above may exist within a single computing system or may be distributed among multiple computing systems. For example, a verification system may be part of a registrar or registry's local computing environment. As another example, a single shared registry system may include components for managing domain name registrations in accordance with whitelist procedures in addition to a whitelist domain name registry system and a non-whitelist domain name registry system. Similarly, a single domain name system server may include registrations for both target domain names and whitelist domain names.

FIG. 1 is a block diagram illustrating an environment 100 in which the disclosed system may operate in accordance with some embodiments of the disclosed technology. In this example, environment 100 includes target shared registry system 110, whitelist shared registry system 120, registrars 130, registrants 140, verification systems 150, shared registry system 160, and network 170. Target shared registry system 110 includes WHOIS database server 112, domain name system server 114, and target domain name registration component 116. WHOIS database server 112 stores information pertaining to the registered users or assignees of various resources, such as registered domain names. Domain name system server 114 translates domain names and hostnames into the corresponding numeric addresses, such as an IP address and can include additional DNS records. Target domain name registration component 116 is invoked by a shared registry system to register domain names on behalf of a registrant and/or registrar. Whitelist shared registry system 120 includes WHOIS database server 122, whitelist domain name system server 124, whitelist domain name registration component 126, and prune whitelist component 128. WHOIS database server 122 stores information pertaining to the registered users or assignees of various resources, such as registered domain names. In some embodiments one or more WHOIS database servers may be replaced by, or used in conjunction with, other systems, such as an RDAP server, an RDDS server, and so on. Whitelist domain name system server 124 stores registered whitelist domain names and can include additional DNS records. Whitelist domain name registration component 126 is invoked by a registry system to register whitelist domain names on behalf of a registrant and/or registrar in response to receiving an indication that the registrant and/or registrar have been pre-approved by a corresponding verification system. Prune whitelist component 128 may be invoked by whitelist shared registry system 120 periodically (e.g., once per second, once per minute, hourly, daily, weekly, monthly) to remove expired whitelist domain names from whitelist shared registry system 120. Domain name verification systems 150 include verify domain name registration component 155. Shared registry system 160 includes WHOIS database server 162, domain name system server 164, target domain name registration component 166, whitelist domain name registration component 167, domain name verification system 150, and prune whitelist component 168. Each shared registry system is managed by a registry operator that manages one or more top-level domain registries. For example, DONUTS Inc. administers “.shoes,” “.domains,” and so on while NEUSTAR, Inc. administers “.us,” “.biz,” and so on. Each registrar 130 manages the reservation of domain names offered by a shared registry system to registrants. For example, ICANN-accredited Internet domain name registrar GODADDY manages millions of domain names on behalf of millions of customers. Each registrant 140 represents an individual or entity (e.g., a corporation) that has registered or would like to register one or more domain names. Each verification system 150 is responsible for controlling or overseeing particular registrations. For example, one verification system may oversee registrations within a particular top level domain (or subdomain), such as “.management,” “.seattle.community,” “.east.kingcounty.community,” and so on. As another example, one verification system may oversee registrations by particular domain registrars or registrants, such as all registrars or registrants within a particular country or jurisdiction. In some cases, each domain name registration system must obtain oversight or control permissions from the shared registry system responsible for the corresponding top level domain. For example, DOMINOS pizza may want to oversee registrations in the “dominos.pizza” subdomain of the “.pizza” top level domain. In this example, DOMINOS PIZZA could request permission from DONUTS Inc. (the registry operator that manages the “.pizza” top level domain) to ensure that, for example, only affiliates or franchisees can register domain names under the “dominos.pizza” subdomain. If granted, DOMINOS PIZZA could establish a verification system to oversee and control registrations within the reserved or protected “dominos.pizza” subdomain. Verification systems may exist to comply with local legal requirements. A registry operator may charge a fee to allow another entity to establish or otherwise use a whitelist domain name registry system. In some embodiments the systems and various components of environment 100 communicate via network 170 or directly via wired or wireless communication connections (e.g., radio frequency, WIFI, BLUETOOTH).

In some embodiments, environment 100 includes multiple whitelist shared registry systems and/or multiple target shared registry systems. In some embodiments, a single shared registry may include one or more whitelist domain name system servers and one or more target domain name system servers. In some embodiments, a single domain name system server may include registrations for both whitelist domain names and target domain names such that registrations for whitelist domain names and target domain names are managed by a single shared registry system.

FIG. 2 is a flow diagram illustrating the processing of a whitelist domain name registration component in accordance with some embodiments of the disclosed technology. The whitelist domain name registration component is invoked by a shared registry system to generate and register whitelist domain names upon determining that the registration of a corresponding target domain name had been pre-approved. In block 210, the component receives one or more commands to register a target domain name, such as a command to register “availabledomain.domains” and/or a command that includes credentials for a registrant, registrar, and so on. In decision block 220, if the registration is subject to oversight or control by a verification system (e.g., if the originating registrant or registrar is subject to legally mandated oversight or the target domain name belongs to a reserved or protected top level domain or subdomain), then the component continues at block 230, else processing of the component completes. In block 230, the component checks with the corresponding verification system to determine whether the registration is approved by the corresponding verification system. For example, the system may send identification and/or credential information to the corresponding verification system along with the target domain name. In decision block 240, if the registration is approved by the corresponding verification system, then the component continues at block 250, else the component continues at block 270, reports that the registration has not been approved, and completes. In block 250, the component generates a whitelist domain name for the registration in accordance with predetermined policies established by the corresponding verification system, the whitelist shared registry system, or another entity. In block 260, the component writes the generated whitelist domain name in a domain name registry and then completes. In some embodiments, a means for registering whitelist domain names comprises one or more computers or processors configured to carry out an algorithm disclosed in FIG. 2 and this paragraph.

FIG. 3 is a flow diagram illustrating the processing of a verify registration component in accordance with some embodiments of the disclosed technology. The manage registration component is invoked to approve or deny a domain name registration request. In block 310, the component receives registration information, including, for example, identification or credential information for the registrant, identification or credential information for the registrar, and/or the target domain name. In decision block 320, if the domain name is approved for registration by the verification system, then the component continues at decision block 330, else the component returns false (i.e., an indication that the domain name is not approved for registration) and completes. For example, the verification system may prevent registrations for domain names that include certain words or phrases. In decision block 330, if the registrant is approved by the verification system to register domain names under its control, then the component continues at decision block 340, else the component returns false (i.e., an indication that the registrant is not approved to register domain names) and completes. For example, the verification system may prevent a particular user or group of users (e.g., terrorists), but not necessarily all users, from registering protected domain names. In decision block 340, if the registrar is approved by the verification system to register the target domain name, then the component returns true (i.e., an indication that the registration is approved) and completes, else the component returns false and then completes. In some embodiments, a means for verifying domain name registrations comprises one or more computers or processors configured to carry out an algorithm disclosed in FIG. 3 and this paragraph.

FIG. 4 is a flow diagram illustrating the processing of a target domain name registration component in accordance with some embodiments of the disclosed technology. The target domain name registration component is invoked to register a target domain name according to whitelist procedures. In block 410, the component receives one or more commands to register a target domain, such as a command from a registrar or registrant. The one or more commands may include, for example, a domain name, identification information for the registrant and/or registrar. In decision block 420, if the domain name is available (i.e., not currently registered), then the component continues at decision block 430, else the component continues at block 485. In decision block 430, if the registration is subject to control by a verification system, then the component continues at block 440, else the component continues at block 490. In block 440, the component generates one or more whitelist domain names for the target domain name and the registration in accordance with whitelist domain name generation procedures established by, for example, a corresponding verification system, a shared registry system, a registry operator, and so on. For example, for a registration request for the domain name “Miami.trips” from a registrar having a previously-assigned unique IANA number of 146 on behalf of a user with the unique identification number of UID5439394, the component may generate a whitelist domain name of:

-   -   (1) UID5439394.146.Miami.trips.valid.zone     -   (2) Miami.trips.UID5439394.146.valid.zone     -   (3) 146.Miami.trips.UID5439394.valid.zone, or     -   (4) Miami.trips.valid.zone.         Examples (1)-(3) include information representing the         registrant, the registrar, the target domain name, and a         whitelist subdomain (“valid.zone” in this example). Example (4)         only includes the target domain name and the whitelist         subdomain. With respect to example (4), the system may store         identification information for the registrant and/or registrar         in association with a registration of the whitelist domain name,         such as in a WHOIS or DNS record. In some examples, the         component may generate multiple whitelist domain names for the         registration, such as:     -   (5) UID5439394.Miami.trips.valid.zone, and     -   (6) 146.Miami.trips.valid.zone.         Each of the above whitelist domain names represents one or more         aspects of the registration, such as the registrant, the target         domain name, and the whitelist subdomain (example 5), or the         registrar, the target domain name, and the whitelist subdomain         (example 6). In block 450, the component queries the         corresponding whitelist domain name registry system to determine         whether the generated whitelist domain name(s) are registered         therein. If the generated whitelist domain name(s) are not         registered therein, then the registrant and/or registrar have         not been pre-approved by the corresponding verification system         to register the target domain name and the request can be         denied. In decision block 460, if the generated whitelist domain         name(s) are registered in the corresponding whitelist domain         name registry, then the component continues at block 470, else         the component continues at block 485. In block 470, the         component compares whitelist registration information to         registration information for the current request. For example,         the component may retrieve registrant and registrar information         from the whitelist domain name registry system and compare the         retrieved information to the information included with the         registration request received in block 410. In some examples,         the component may rely on the use of whitelist domain name(s)         generated using unique registrant and/or registrar         identification information (e.g., both during registration of         the whitelist domain name(s) and in block 440) to validate the         registrant and registrar. In decision block 480, if the         registrant and/or registrar are approved to register the target         domain name, then the component continues at block 490, else the         component continues at block 485. In block 490, the component         writes the target domain name to a registry and then completes.         Thus, if a party registering a target domain name is not subject         to control or oversight by a verification system, that party may         be able to beat a party subject to control or oversight by the         verification system to the registration if, for example,         approval by the verification system is delayed. In block 485,         the component reports an error message and then completes. In         some embodiments, a means for registering target domain names in         accordance with a whitelist domain name registry system         comprises one or more computers or processors configured to         carry out an algorithm disclosed in FIG. 4 and this paragraph.

FIG. 5 is a flow diagram illustrating the processing of a prune whitelist component in accordance with some embodiments of the disclosed technology. The prune whitelist component is invoked periodically (e.g., once per second, once per minute, hourly, daily, weekly, monthly) to de-register whitelist domain names that have expired due to their corresponding target domain names having not been registered in a predetermined timeframe. For example, a whitelist domain name may expire after one year if its corresponding target domain name has not been registered. In block 510, the component identifies domain names in one or more whitelist domains (or subdomains), such as “valid.zone,” “whitelist.zone,” “preapproved.works,” and so on. In blocks 520-560, the component loops through each of the identified domain names and de-registers the expired domain names. In decision block 530, if the corresponding target domain name for the currently-selected whitelist domain name is registered, then the component continues at block 560, else the component continues at decision block 540. In decision block 540, if the whitelist registration has expired, then the component continues at block 550, else the component continues at block 560. In block 550, the component removes the currently-selected whitelist domain name from the whitelist domain name registry system. In block 560, the component selects the next identified domain name and if all of the identified domain names have been selected, processing of the component completes. In some embodiments, a means for pruning a whitelist registry comprises one or more computers or processors configured to carry out an algorithm disclosed in FIG. 5 and this paragraph.

These and other changes can be made to the invention in light of the above Detailed Description. While the above description describes certain examples of the invention, and describes the best mode contemplated, no matter how detailed the above appears in text, the invention can be practiced in many ways. Details of the system may vary considerably in its specific implementation, while still being encompassed by the invention disclosed herein. As noted above, particular terminology used when describing certain features or aspects of the invention should not be taken to imply that the terminology is being redefined herein to be restricted to any specific characteristics, features, or aspects of the invention with which that terminology is associated. In general, the terms used in the following claims should not be construed to limit the invention to the specific examples disclosed in the specification, unless the above Detailed Description section explicitly defines such terms. Accordingly, the actual scope of the invention encompasses not only the disclosed examples, but also all equivalent ways of practicing or implementing the invention under the claims. In some cases, various steps in the algorithms discussed herein may be added, altered, or removed without departing from the disclosed subject matter. Those skilled in the art will appreciate that features described above may be altered in a variety of ways. For example, the order of the logic may be rearranged, sublogic may be performed in parallel, illustrated logic may be omitted, other logic may be included, etc.

To reduce the number of claims, certain aspects of the invention are presented below in certain claim forms, but the applicant contemplates the various aspects of the invention in any number of claim forms. For example, while only one aspect of the invention is recited as a means-plus-function claim under 35 U.S.C § 112(f), other aspects may likewise be embodied as a means-plus-function claim, or in other forms, such as being embodied in a computer-readable medium. (Any claims intended to be treated under 35 U.S.C. § 112(f) will begin with the words “means for”, but use of the term “for” in any other context is not intended to invoke treatment under 35 U.S.C. § 112(f).) Accordingly, the applicant reserves the right to pursue additional claims after filing this application to pursue such additional claim forms, in either this application or in a continuing application.

From the foregoing, it will be appreciated that specific embodiments of the invention have been described herein for purposes of illustration, but that various modifications may be made without deviating from the scope of the invention. Accordingly, the invention is not limited except as by the appended claims. 

We claim:
